this is identical BUT I CANNOTFIND THEIR WEIRD DANCE ON THE INTERNET

I see them around the school in florida. they hop around and fly looking for food. but when they sit around they mame loud clicking noises and weird noises from flapping their wings agianst their chest. the look really territorial and have "standoffs" where they walk around one another in circles withtheri beaks raised upward. WHAT ARE THESE GUYS CALLED?
